  • Ethernet communication device with reduced EMI
    Patent number: 8774016
    Abstract: A network device includes a physical layer transceiver configured to receive incoming data on a data link at an input clock rate and to store the incoming data in a buffer. The physical layer transceiver includes a Media Independent Interface (MII) controller configured to receive the incoming data stored in the buffer and to transmit the incoming data over a MII bus based on a MII clock where the MII clock is a spread spectrum clock. The network device further includes a Media Access Control (MAC) device configured to receiving incoming data from the physical layer transceiver over the MII bus where the incoming data is clocked by the spread spectrum MII clock.
